Last night, Stephen Colbert pointed to President Obama's record of authorizing five times as many covert drone strikes as President Bush, noting that "we all know that Barack Obama has been working hard to kill our economy, but it turns out there is something he's working even harder to kill."

One possible explanation for all of the strikes? Colbert pointed out that since Obama has not fulfilled his promise to close Guantanamo Bay, the drone strikes are a handy solution: "It's brilliant. He doesn't have to worry about habeas corpus, because after a drone strike sometimes you can't even find the corpus."
